ESPHome-Devices

Gosund SP112

Gosund SP112

Device Type: switch
Electrical Standard: eu

Flashing

The device can be flashed using tuya-convert. Fresh out of the factory it will be in autoconfig mode. When plugged in for the first time tuya-convert will pick it up directly.

If that doesn't work out for you, disassembly and wired flashing is explained in this (German) video.

Attention: As it turns out Tuya no longer builds them with esp chips. This means as of late 2021 you cannot flash esphome on new units.
